How can I test Rails Routes with Minitest?

Question

I'm trying to use Minitest for an existing Rails app (3.2), but not having any luck running routing tests. I've tried rspec syntax (should route_to) and TestUnit syntax (assert_routing) but no luck.

Any advice on getting this to work? Specific modules I need to include, etc?

thanks

Answer 1

If you are using minitest-rails you can create route tests by placing the following in test/routes/homepage_test.rb:

require "minitest_helper"

class HomepageRouteTest < ActionDispatch::IntegrationTest
  def test_homepage
    assert_routing "/", :controller => "home", :action => "index"
  end
end

Alternatively, you can use the Minitest Spec DSL:

require "minitest_helper"

describe "Homepage Route Acceptance Test" do
  it "resolves the homepage" do
    assert_routing "/", :controller => "home", :action => "index"
  end
end

You can run these tests with the following rake task:

rake minitest:routes

@blowmage's answer helped me but it looks like the syntax has changed a bit.

With Rails 4:

require "test_helper"

class HomepageRouteTest < ActionDispatch::IntegrationTest
  def test_messages
    assert_generates '/messages', :controller => "messages", :action => "index"
  end
end
